The search of the wreck of the Costa Concordia began again at dawn on Saturday, a week after the cruise liner came to grief on the rocks off Italy’s Tuscan coast.
Work was suspended on Friday after the vessel shifted slightly on its rocky ledge.
The delay has further complicated the work of divers who have already been hampered by poor visibility, floating objects and underwater debris.
Coast guards say there is only minimal hope of finding anyone alive: even if there are any air pockets below the surface, the water temperature is extremely low.
“We found the bodies of 11 people and will continue the search for the 21 still missing. We still hope that there’s someone still alive; maybe somebody already returned home but didn’t make himself known. We’ll continue the search until we’re absolutely sure there’s no-one left inside,” said coast guard spokesman Filippo Marini.
In particular rescue workers are looking for a missing five-year-old girl and her father.
The search could be further threatened by more bad weather expected over the weekend.
